    • An image forming apparatus including: a photoreceptor for bearing a toner image; a transfer body onto which the toner image borne by the photoreceptor is transferred; a drive section for driving the photoreceptor and transfer body respectively, and a control section for controlling the drive section so as to drive the photoreceptor and transfer body at a predetermined driving speed, wherein the control section, under a state in which the control section controls to drive the transfer body at the predetermined driving speed, controls to: a) drive the photoreceptor while changing the driving speed of the photoreceptor within a range of driving speeds between low speed and high speed, including the predetermined driving speed, b) extract torque characteristics under the control which includes the change of driving speed of the photoreceptor, and c) determine the driving speed of the photoreceptor based on the extracted torque characteristics.
    • 一种图像形成装置,包括:用于承载调色剂图像的感光体; 其上转印有由感光体承载的调色剂图像的转印体; 用于分别驱动感光体和转印体的驱动部分和用于控制驱动部分以便以预定驱动速度驱动感光体和转印体的控制部分,其中控制部分在控制部分控制的状态下 以预定的驱动速度驱动转印体,控制:a)在包括预定驱动速度的低速和高速的驱动速度的范围内改变感光体的驱动速度的同时驱动感光体,b)提取转矩 包括感光体的驱动速度变化的控制特性,以及c)基于所提取的扭矩特性确定感光体的驱动速度。
